经典的AX-CPT任务测量两种形式的认知控制：持续的目标导向控制（“主动”控制）和突发事件后认知控制的短暂变化（“反应”控制）。我们通过添加负面和中性的国际情感图片系统（IAPS）图片来评估负面情绪对这两种形式的认知控制的影响。基于行为和电生理学指标，包括N2事件相关电位分量和源空间激活（低分辨率断层扫描[LORETA]），评估主动和反应性控制方式。我们发现，相对于中性刺激，消极的反应时间较慢，DLPFC激活更大。此外，我们发现，在主动维护之前提示的信息期间，主动式反应风格与较少的前额叶激活（解释为反映处理效率的提高）有关，而反应式反应风格与较少的前额叶激活（解释为反映处理效率的提高）有关。在即时环境触发的信息期间。这种结果模式在相对中性的情境中很明显，但在面对负面情绪时，这些关联并没有被发现，这表明潜在的反应风格与情绪的相互作用对前额叶神经激活的影响
The canonical AX-CPT task measures two forms of cognitive control: sustained goal-oriented control (“proactive” control) and transient changes in cognitive control following unexpected events (“reactive” control). We modified this task by adding negative and neutral International Affective Picture System (IAPS) pictures to assess the effects of negative emotion on these two forms of cognitive control. Proactive and reactive control styles were assessed based on measures of behavior and electrophysiology, including the N2 event-related potential component and source space activation (Low Resolution Tomography [LORETA]). We found slower reaction-times and greater DLPFC activation for negative relative to neutral stimuli. Additionally, we found that a proactive style of responding was related to less prefrontal activation (interpreted to reflect increased efficiency of processing) during actively maintained previously cued information and that a reactive style of responding was related to less prefrontal activation (interpreted to reflect increased efficiency of processing) during just-in-time environmentally triggered information. This pattern of results was evident in relatively neutral contexts, but in the face of negative emotion, these associations were not found, suggesting potential response style-by-emotion interaction effects on prefrontal neural activation
